Molecular structure of germanium dibromide: A reinvestigation

The electron diffraction intensities of germanium dibromide [1] were reanal yzed based on computational evidence on the geometry of the excited state m olecule. It was found that beside the ground state germanium dibromide mole cule a small amount of iron dibromide, rather than other germanium dibromid e species, may have been present in the vapor. The revised geometrical para meters of GeBr2 are: r(g)(Ge-Br) = 2.359 +/- 0.005 Angstrom and angle(a)Br- Ge-Br = 101.0 +/- 0.3 Angstrom.
